    Study Notes

    Exercise Physiology and its History

    • Exercise Physiology is defined as the study of the physiological responses and adaptations that occur during exercise or physical activity.
    • Hippocrates is considered the 'Father of Modern Medicine'.

    Energy Systems

    • The energy system with the highest capacity and longest duration is the oxidative system.
